A pendulum made of a uniform wire of cross sectional area A has time T. When an additional mass M is added to its bob, the time period changes to `T_M`. If the Young's modulus of the material of the wire is Y then `1/Y` is equal to:

A

`[1-((T_(M))/(T))^(2)](A)/(Mg)`

B

`[1-((T)/(T_(M)))^(2)](A)/(Mg)`

C

`[((T_(M))/(T))^(2)-1](A)/(Mg)`

D

`[((T_(M))/(T))^(2)-1](Mg)/(A)`
